RC: Navring rework. - AOKP

PS1: Better interface for users.
     Get drawables from FW.

PS2: Added logic for tabletui and layouts (may need tweaking)

PS3: Cleaned up strings
     Added long and short discriptions to the pop up dialogs
     Since long press action have no icon I made a friend uri toast
     message to let user know a long press action was set.

PS4: simpify the dialogs a bit. still need to fix custom icons...

PS5: Fixed custom Icons did more dialog work.
     only 2 things left. tabletui/landscape layouts need tweaking
     need to move target selection and enable longpress inside the new
     ui. Getting close this is pretty functional.

PS6: Adjusted custom icons size.
     Moved Enable long press and amount inside the ui
     moved Navigation ring to its own header in main activity

PS7: Cleanup a bit.
     fixed crashing on changing target values
     Now using a spinner and switch for target number and longpress

PS8: Comment clean up.

PS9: use one content resolver instead of like 12....
     Switched to enum and switch case for dialog functions

PS10; rebase off new awesome action. clean up things Jon pointed out
      added icons from Nitroz

ps11: get rid of one last hardcoded string

ps12: Rebase

Layouts:
- Phones: use portrait in any mode to configure. It is that simple:
the ring just cannot fit in landscape because the drag handler
is always in the middle of the glowpad and if we want one that fits,
that would be just too small.
- Tablets: tablet/phablet looks ok, phone mode is weird.
I bet nobody uses that anyways.

That's all I could do, tested on mako and grouper.
